Thanks to it’s latest coat of paint, the Old Telegraph Office, also known as the Dead Letter Office, is now virtually impossible to miss. Located at the corner of Dalhousie Square East and Dalhousie Square South, with a 120 feet tall bell tower, the remarkably beautiful and ornate building was constructed between 1873 and 1876. It served as a sort of sorting office for all international mail coming in to Bengal, and when letters could not be sent to someone because of errors in the address, and couldn’t be returned to the sender, they ended up here.
The postal department is still using the building, but there are no restrictions on photographing the building from the outside. And do try the tea from the stall across the road. He makes it with green cardamom, and early in the morning, it's just what you need.
